Hi
I spent a few hours last night trying to work out why a particle effect was not working. I eventually worked out that it was contained as part of a hidden layer.
Un-hiding the layer makes the particles visible though I cant move them from the layer.
Not sure why. PFlow source icon is in correct layer and the object based emitter i am using are in the correct layer but the particles themselves remain in another layer. There is nothing in the layer list that refers to these particles either - weird.
Got no idea why they moved to this layer either.
Anyone know what's going on here?

Everything PFlow creates in teh Particle View has an invisible counterpart in the form of a helper.

For instance you can see them if in a new scene you create a Standard Flow and do a select all in the viewport. You will notice in the Command Panel that you have 13 Entities Selected, yet you only "see" the PF Source icon.

There are some script snippets out there that select all of these, as well as a few functions in max (Synchronize layers) that are supposed to deal with it in one way or another.

I wrote a script a little while back that will move everything to the layer that the PF Source is on and reports everything it did to the listener, I just cleaned it up a little, try it if you like, it does not have an interface yet, so just run from the maxscript run menu or open it in the editor and evaluate it.
